The roll member B includes a shaft 38 which is journaled inbearingblocks23 and ai'pluralityof r011 heads K and an idler 39.

Each rollhe'ad K.,isconstructed in accordance with the-illustration inFig. 4 and comprises-two sections {t0 each of which come prises an innerhubcylinder 41 having an outwardly directed annular flange 42 at itsinner, edge merginginto a cylindrical rim 43 disposed concentricallyabout the hub cylinder in spaced relation thereto.

Of course,these-shafts may bedriven in an-ysuitabl'e manner and the example of thedrive shown herein jis not of the essence. of the invention. In-,:u.singthe device the veneer may be temporarily placed on the tray framet) andpi'eceslifted therefrom and guided over-the feed roller 20 to. engagebetween whichever heads H and K desired of the roll. members Aa-ndB. f

The heads K are fixed tothe shaftv 38;by set screws 50 threaded,through, openings in the hub cylinders 41 as is clearly shown-inFigifet... It is preferable that thehe-ads H and K; have their sectionsformed by cast ings although this is. not of the'essence'of theinvention.

It isthoughtthat the construct-ion utility;

' j operation, and! advantages of" the invention will; now? be clearly,understood without a more detailed description?- thereofl The presentembodiment' of the invention; has been; disclosed'in j detail -me rely-- by way of example, since in actual: pna'ctice; it-attains. thefeatures of advantage enumerated ascdes the above description. .It'willbe apparent,

however, that numerous'changes in the detailsof construction, and in thecombination an'djarran'gement of parts may be resorted to without departng" from the "splrit or scopeof-the invention as hereinafter claimed orsacrificing any of its advantages.
